I've had a lot of tablets doings stuff like this, my company uses them as "thin clients" so we mod them heavily. Try this:
1, Do a battery pull
2. Power on the phone, keep holding the power button
3. Listen closely to any kind of pop / click (caused by phone being switched off, this creates a power spike sometimes leaking onto speaker)
4. Connect to pc via usb
5. See if there's ANY activity on usb (in windows via device management)
6. Try to get into fastboot / restore RUU
Because of a modified kernel or rom the display driver might have gone pear shaped, this makes devices appear bricked.
Hope this helps, good luck

Well I tried to pull out and in the battery and I kept holding the power off button( i feel a vibration, but nothing happens). When i connect the phone my computer it says USB device not recognized or stuff like that, i cant connect it to fastboot.

Nice news

touch2 hang on 3 color boot mode :(

hi all : i have one set of HTC MEGA TOUCH 2 that it hang on 3 color boot menu.
i can't do hardspl or flash any flash file on to it , plz help me what should i do ?
1) When the phone is off, press and hold the button VOLUME DOWN (left side of the phone).
2) While holding the volume button, you press short the ON / OFF button and let it go.
3) If you see a warning message on the display, release the VOLUME-button
4) Press the VOLUME UP button to perform the reset or press any other key to cancel the reset.
Good luck....
I have a HTC Touch2 that is tuck in the Bootloader.
I have removed the battery and attempted the hard reset, as soon as it comes on it goes straight to the bootloader screen.
If the phone is connected to the PC, it says USB in the white band.
If not is says serial.
No SD card fitted, no SIM card fitted.
Any ideas?
Flash with a stock ROM in USB-mode should work for you
I thought you could only flash via USB if the device has been Hard-SPL'd? and you need to have an activesync connection?

Flashing with a stock ROM works without Hard-SPL, and as far as I know you can flash it when it says 'USB' in the bootloader mode. Correct me if Im wrong or else try...
To be honest, I fixed the phone without doing any of that. There seemed to be a problem with the USB port on the phone. I disconnected the battery and put some alcohol into the port (IPA!! not beer - lol) left it for a few seconds and then cleaned it out with compressed air. When I put the battery back in, it booted up fine.
wow... nice
why the usb-port?
strange...
hey guys, I see I have a problem from the damaged tape volume, so how can I make HR and enter bootloader
solved!

This man is my hero. I *very* carefully extracted a little bit of lint that was stuck right at the back of my HTC USB port in my touch2, with a drawing pin (tack for the americans).
While I would not reccomend using a pin, as it may damage the port, it fixed my phone right up, it now no longer gets stuck on the bootloader (tri-colour screen), and it also fixed a problem in which I got a reccurring error telling me to remove the USB headset as it doesn't work (or something to that effect) while nothing was actually plugged into it.
Thanks again, hogman!
edit: I can't figure out how to give you thanks rating or whatever it is, so this will have to do. Yes, I'm a noob!

Please save me!!!

i think is been discuss before, so please don't hate me for this post.
I was on Nero v2, I was trying to flash back to stock, i didn't know i had a hardware locked vibrant, so when i was in odin, my phone got stock in cache.rf something like that, them shut off, now I have a phone to computer w a yellow triangle in the middle, i can't get to put my phone back to download mode to safe my life. Please any advice.??
*BTW: i tried every possible combination that i found here, but nothing.

I thought that too then I remembered this is not a religious forum.
Anyway, sounds like you will need the jig, read up in the bible sticky (now that does sound religious) if the other ways to get you into recovery do not work, then the jig will do it.. You could just go get a 301k resistor use a wooden toothpick and shove it into the usb side between to 2 contacts (2&4?) and then plug into your phone and that will work check on the link the above sent you. don't worry you will get out of this, I only know of handful of people who really bricked the vibrant and they are super tweakers.......this is solvable.

You need to get into download mode:
try this:
reboot your computer
pull the battery on the phone and leave it out
plug in the usb to both comp and phone
hold both volume keys
put in battery while holding the volume keys
That should get you into download mode
Then odin this:
http://forum.xda-developers.com/showthread.php?t=803492
MAKE SURE you click the PDA checkbox not phone when you odin.
im not sure that I have hardware mode but to get to download mode.
I pull the battery to make sure the phone is off. Hold the volume key and plug in the cord. Make sure you have odin with all the proper files ready to go ... Once you plug in and see that you have a com.. you can just hit start. Oh and pull your simcard and sdcard out also.
aslong as you see that phone and computer symbol your phone is never dead.

[Q] S4 Broken Screen - ADB Not Working - Cannot Activate Debugging

Been trying for hours now to try and sort out an issue I am having. My S4 is damaged, the phone works but the screen and digitizer is broken. I want to check a few sms messages, access and control the phone from my PC and basically make a complete clone/image of my phone. I cannot for the life of my figure out how to do this.
I use windows 7, I have installed SDK tools, have ADB/fastbook etc. Device isn't found with ADB. Spent hours reading information about installing correct drivers, which I have done. No luck what so ever. The phone is not rooted, developers tools is not on, usb debugging is not on either.
I am starting to think this is a lost battle as I cannot sort this out.
Any ideas?
Thanks
Bump.
Anyone? Is there no way to solve this problem? Tearing my hair out.
Best bet (given ADB doesn't work) would be to root the phone & get a custom recovery on (via Odin; this is might be very difficult if you can't somehow have the phone & PC recognise each other - you don't need to have had debugging on though) then do a nandroid backup (someone using the same recovery/version might be able to walk you through the button presses.
What S4 variant (model number) are we talking about ?

GT-I9505 is the model number that is displayed behind the battery. The screen is broke and so is the touchscreen (completely black). I tried to figure out via ODIN but that wouldn't recognise the phone either. I assumed you'd need to boot in recovery/download mode but because I cannot see anything on screen, when I do the volume down, home and power thing I do not know what to do next so the phone boots up normally. I know this because I have unread SMS and when phone loads my SMS tone goes off.
Really not sure how to get around this.
You're going to have to get it into DL mode somehow (don't need to use home button on S4, just vol down/power); try a jig. Once you've done that, then you need to get the phone & PC to recognise each other. If you're having problems with that, prepare to continue to do a lot more reading/trying stuff if you're having PC-side driver issues (there's a lot of threads on here re: the issue). There's also an 'Odin troubleshooting' guide in S2 General by Hopper8 which is worth looking at as much of the stuff he suggests also holds true for the S4 (except the firmware stuff, which is obviously different).
There's not going to be any quick & easy in this instance, I'm afraid. It's going to be hard work.
Edit - Also..USB board/port on the phone might also be damaged, so when you reach the point of having tried everything on the PC-side & everything you can possibly try on the phone-side, replace the USB board/port on the phone. This is quick/easy/cheap (<US$20) to do & might just enable you to get things done where everything else has failed.
Extra edit - And...A jig working (getting you into DL mode) or not is probably a good test of whether the USB board/port on the phone is still good; I.E if the jig works, the board/port is probably still good, if it doesn't, the board/port might be shot as well.
The USB is fine because when I plug the phone in when in normal boot it recognises the data storage. I will try to boot in DL mode. Are there any gestures my S4 will do when booting in DL? Vibrations? As I cannot see anything on screen that will indicate it's worked. I think that once I can get the phone to work with ODIN/ADB I will be good to go as I am relatively tech savvy.
Nope. You're going to by flying blind so far as having no screen/no vibrations in DL mode goes. You're going to be relying on the jig working, and once you hook it up to the PC & fire up Odin, you'll know straight away whether you've got a successful connection up & running (as screenshots in the many Odin guides on here will show you).
I see, will just have to keep trying.
So on the S4 it's hold power and volume up, then wait? or do I need to press anything else afterwards? Or is it power and volume down?
Thanks
No luck with download mode. Girlfriend has a note 2, and her method is Vol down, home and power button. Screen comes up almost immediately with confirmation. Volume up needs to be pressed to confirm. Tried to replicate with S4, no avail.
No luck with starting S4 in download mode. I have followed video on youtube. Supposed to be Vol Down, Home and Power button. Wait till vibrate and warning screen, then press up. Because I cannot see the screen I cannot see the warning screen. But I Hold for 4 seconds, release just after vibrate and then press up, but phone seems to boot up in normal mode.
Ok, finally in download mode, now what? I know it works because it installed new drivers and device manager states a samsung modem. Need to try and clone and do what I need to do ASAP and taking to store tomorrow to exchange for new one.
Any last minute ideas?
Thanks
ODIN3 v1.85 shows a yellow box, this is good right? I downloaded CWM from http://galaxys4root.com/clockworkmodtwrp-recoveries/
What do I need to do next, do not want to make this worse, I just need to enable usb debugging or at least be able to use adb, I am good to go from there
Only a few hours left? Surely someone knows what Flash I need to do to allow me adb access???
Right, go into recovery mode...adb now works.
What do I need to do to enable debugging?
Edit:
I can't get adb to work... error: closed
any ideas
If you cant get adb to work in recovery then youre out of luck.
Incase this happens with new phone, always have a remote access app like Cerberus installed. MightyText is a pretty nice app too.
I see, ok no worries. Thank you anyways

Z5C will not charge at all

In my persistent attempts to put a custom rom on this device, the following sequence occurred:
- Phone suddenly not recognized by PC in any mode: normal, recovery, or fastboot. It would not even charge from the USB port, no reaction at all from the phone or PC that the connection is made. Other devices using the same port and cable work correctly.
- Phone unresponsive to a wall charger while it is powered on. Similar to the above description, the phone does not recognize that it is pulled into a charger at all while it is powered on. However, at this point the
- Phone is responsive to a wall charger after turning it off. The screen shows the charging icon on screen and the LED is red, meaning the phone recognizes the micro-USB connection when it is powered off, but only via the wall charger, still sees nothing when connected to the PC.
With the above criteria I decide to let the device completely discharge its battery, hoping that a full empty to full charge will reset whatever is happening. It takes about 3 days to go completely dead ... moving from screen need-charging image, to only the red LED, to absolutely no response when pressing the power button.
Now I have a phone that is completely unresponsive to any button press, as expected since the battery is completely drained. Unfortunately, it no longer responds to the wall outlet at all. Meaning it won't charge in any way. Used multiple chargers, multiple wall sockets, multiple cables, gave it compliments, etc.
At this point the phone is totally and completely dead and unresponsive to any charging. Any thoughts or help?

Thank you for the response, I was about to throw the phone away. Can you be a little more specific? I see your post here regarding a rebooting loop with red light flashing. However, I don't have any response from the phone whatsoever ... nothing on the screen, or led in top right. It does not accept a charge from 1A or 2A source, it is literally a paper weight right now. I need to "jump start it" or something of this nature. It won't charge at all.

Probably the phone looks dead but does get charge - it's just not showing it with the LED.
I believe Snapdragons are close to impossible to hard-brick - the chip itself has a ROM with EDL burned into it and that can always be used to bring it back from zombieland, if you have the right tools. But if you are lucky enough, then service mode would still be available even without hunting for the EDL stuff.
First, power the phone off for real with the hidden button near the SIM tray - and leave it off.
Then, install Flashtool and use it to flash a stock ROM, as described for instance here. When flashing, choose flashmode instead of fastboot and follow the instructions.
HTH,

Thank you for the response. I pressed the hidden button in the SIM tray for 10 seconds, 3 times in a row. Downloaded the latest "Emma" Sony Flashtool ... and nothing happens. The software does not recognize any Sony device plugged into the computer. Checked the USB cable, it's good. The computer, and the Sony flash software, do not recognize the device at all. It will not turn on in any way, and it does not appear (based on the screen and LED) to accept a charge at all. It truly seems bricked at this point. Any thoughts?

I don't know what method is used by Sony Emma, sorry. But simply connecting the phone won't surely be enough if there is no software on it that answers to USB requests from your PC.
How about trying with the tool I suggested you? Let the phone off, download a stock firmware and start the flashing in flashmode instead of the standard fastboot mode (just follow the on screen instructions).
If that does not work, the only thing that's left is EDL mode. I've found no documentation for Z5 Compact, unluckily - but any decent repair shop should be able to resurrect it.

I downloaded the flashtool you linked, and also the XperiFerm and latest Z5C drivers as mentioned in the tutorial. The drivers do not have an exe. I can not manually install the drivers because the device is not recognized by the PC at all, it does not show in the Device Manager. Moving forward ... downloaded and installed the Sony Xperia Companion software, it also does not recognize the device at all. The flashtool you linked also does not see the device at all.

There is no flashmode or fastboot mode possible, the device does not respond to any buttons, any charge, or mean glances. Any last thoughts before I cut my losses and throw it away for a XZ1 compact?

Don't throw the phone away!
I fear I was not explicit enough:
1. keep the phone off and disconnected
2. click on the Flash icon, choose the firmware
3. choose flashmode
4. press volume down and only then connect it to the PC
If even this alternative service mode has been wiped, then the only possibility left is EDL. For that, I'd go to a repair shop.

Hi,
Power off the phone : press volume up and power button. Wait 3 vibrations (if not, the phone is powered off).
Press first the volume up and plug the phone with the usb cable into your computer. If you see the blue light you can use Flashtool, if not... it's dead (for me)...
How to use Flashtool is another thing, blue led is essential.
You'd rather throw it away for a Xz2 compact and install Omnirom. You can find some used ones for good prices.

Thanks, Antonio. Step #4 causes no reaction in the phone, or the Flashtool. The software does not recognize the device and the phone remains unresponsive. It truly seems hard bricked to me. I live in Mexico ... this device is rare even in the US, the guys will have never seen it, and their approach to EDL is as good as mine. I'm pretty frustrated with this dead phone, I think it's time for a new one and to mark this as a lesson learned.

Thank you. No blue light under any button combination, charging cable, outlet, software, mean glances, etc. My next one is XZ1 or XZ2 ... I'll take your advice into consideration, the XZ2 has better specs but of course its +$100. I like to think of myself as a capable engineer, but destroying this Z5C has made me pretty hesitant to attempt the same process on a new phone. Everyone seems to agree that hard bricking this device is near impossible, however I beg to differ as look at this dead one on my desk.

Ouch - a real pity.
It really seems you succeded in wiping out all possible accesses for the Sony bootloader. Do you mind me asking how you managed that? I'd like to avoid doing the same mistake.
Qualcomm EDL mode is surely there, but you will need to open the phone and the software for that approach is not freely available (or at least I was not able to find it).

I don't remember the exact sequence, but "fastboot erase" was used on the "bootloader" and "recovery" partitions, then the phone was unplugged. This left the system with no start sequence ... when I depleted all the battery charge it simply wouldn't respond to anything and has since been lifeless. I'll pry it open and take a look at the internals just for fun and to get one last squeeze of value from it. I also plan to bash it with a hammer which will be particularly satisfying.

You can safely overwrite boot, but never ever touch the bootloader. The bootloader is responsible for starting all the various programming modes, as well as passing on execution onto the kernel start during normal boot.
BTW, I don't think there is any reason at all for erasing partitions - when you overwrite them with your own data they will end up being clean anyway.

While I can understand your frustration, that would be quite silly. Even if it has no value to you, it's still recoverable for anyone with the skills and tools - try to sell it instead, if anything it could be used for spare parts.

I'm trying to find out more information about the emergency recovery mode for Z5C - I might be able to find out a way to recover your phone. If I'm successful (be warned, it's a big if - so please don't count on it), you could sell it as a working phone instead of as a brick.
First problem, I don't know how to enter EDL mode on the Z5C: but I hope an EDL cable could work. I've ordered one for testing, since it's an useful tool for recovering a lot of other phones too - it will take a while to deliver, so don't hold your breath. You could also join me in my experiments (after all, you have nothing to lose) by ordering one yourself (you can find cables for as low as 3$).
Second problem, the software tools. Given the ubiquity of Qualcomm chips, apparently there are quite a few available. In the opensource arena, I've found those:
https://github.com/96boards/documentation/blob/master/consumer/guides/qdl.md
https://github.com/openpst/sahara
https://github.com/bkerler/edl
Third problem, finding the signed binaries you have erased from your phone. I guess they can be extracted from my own device quite easily - they are on eMMC after all.
For an in-depth discussion of EDL mode, geared towards its (in)security, I've been reading Aleph Security articles here.

Thank you for the response, I was about to throw the phone away. Can you be a little more specific? I see your post here regarding a rebooting loop with red light flashing. However, I don't have any response from the phone whatsoever ... nothing on the screen, or led in top right. It does not accept a charge from 1A or 2A source, it is literally a paper weight right now. I need to "jump start it" or something of this nature. It won't charge at all.

Hey again, sorry for late reply. Work...
My issue seems totally unrelated to yours. My problem was that I was doing the flashing wrong, instead of just flashing the entire .zip I flashed boot file etc and this is what started the issues with not taking charge, BT wasn't working, wifi etc. But I had more juice in the phone since you want to have quite a bit before doing flashing, but I read your post about discharging it.
If you can't revive it, don't fear rooting and flashing, just make sure to read and to take all steps necessary. I kinda messed up my Z1C and I didn't do any changes to my Z5C until recently. Well, maybe a year now, just because of that occurrence.

I'm trying to find out more information about the emergency recovery mode for Z5C - I might be able to find out a way to recover your phone. If I'm successful (be warned, it's a big if - so please don't count on it), you could sell it as a working phone instead of as a brick.

Wow, you're a true engineer, never give up! Consider my phone part of your testing devices. Please confirm this is the correct EDL cable to purchase for the Z5C: EDL cable for all Qualcomm phones ... It will take a few weeks to get in my hands.

Hello, got my cable - but I've not been able to make it work so far. It could be because I need Windows and specific drivers, I'll look into some more. But yes, when it's fun I never give up

Turning on device without power button

Hi all!
My device’s power button is misfunctioning, and in the future my phone will probably run out of battery.
Thus, I need to find a way to turn on my device without using the power button.
I have read a lot, and I think that there are 3 ways of doing so:
Using Samsung 300K Tool (https://forum.xda-developers.com/galaxy-note-8/how-to/samsung-300k-tool-t3847487) – This option is not working for me, the software doesn’t read my phone.
Entering Download Mode – It is supposed that when pressing Volume Down + Home + Pluging in the phone, it will enter Download Mode, but I have been unable of doing so.
Using ADB – When the phone is off, the device doesn’t appear in the list when typing adb devices.
I think that is a driver problem, but I have installed the drivers from here (https://samsungusbdriver.com/download/samsung-driver-v1-7-11-0) and when the phone is turned on, ADB recognizes the phone perfectly, it is listed as “device”. I suppose that the driver problem is only when the device is off, because when I plug the phone turned off, windows throws a message saying “USB device not recognized. The last USB you connected malfunctioned, and Windows does not recognize it”. I have tried to install manually the drivers, but it said “You have the best drivers already installed”. Also, I have enabled USB Debugging.
Does anyone can help me? Maybe I’m missing something (some configuration parameter or whatever) that prevents the PC to recognize the phone when it is turned off?
Thank you very much in advance!!!
If the phone is off ADB can't work, that's not a driver problem.

thats what we do homie!! i remember fixing a "hard bricked" S3 back in the day with my jig. The mystery of a "hard bricked" phone was "unsolvable" before the jigs became widely known along with the recovery image (which im sure i still have on a hard drive somewhere LoL)
